[asterisk-dev] Determine Useragent of a peer?

[Ulyssees]

I've been searching everywhere, but couldn't find any reference, sorry if I
missed something obvious.

Is it possible to determine the used Useragent of a peer that registered
with Asterisk? It's being saved obviously and can be seen with sip show
peers , but isn't it stored to some variable? or are there other means to
retrieve that information so that it can be used in a dialplan for special
treatment for example?

If not it would be great if this could be added.

Thanks!
